Abstract
A sensor system comprises a plurality of sets optical sensors arranged on an integrated circuit, the plurality of sets optical sensors having a respective top surface. The sensor system further comprising an interface between the plurality of optical sensors and a processing device configured to transmit information there between and an array of optical filters having a respective bottom surface and a respective top surface, where the bottom surface of the optical filter array is located proximal to the top surface of the plurality of sets optical sensors and each optical filter of the optical filter array is configured to pass a target wavelength range of light to a set of optical sensors. The processor is configured to receive an output from each optical sensor in a set of optical sensors and determine a corrected filter response for the set of optical sensors using crosstalk from light transmitted through optical filters adjacent to the set of optical sensors.
